"Cloud Curve" structure. Unlike conventional flat pillows, the ergonomic, cloud-like soft curve naturally fits from the neck to the shoulders. It gently fits the gap in the neck, reduces unnatural postures, and supports the reduction of stress on the body. It also smoothly supports turning over during sleep, helping you wake up feeling refreshed in the morning. 3D Zone Support ● [Back Sleeping Zone] Envelops the head and relaxes the neck, which is tired from the day. ● [Side Sleeping Zone] Maintains the spine in a natural posture and disperses pressure on the shoulders and face. ● [Arm Rest Zone] A natural place for the arms, making it easy to turn over. Firmly supporting low-resilience material. Uses 53D density TPE material. Even if weight is applied, it quickly returns to its original shape, making it easy to turn over. Two heights for the perfect pillow. The pillow has two sides, high and low. The high side is ideal for back sleeping, and the low side is ideal for side sleeping. You can choose according to your body type, sleeping posture, and physical condition of the day. It achieves two types of comfort with one pillow, making it easy to find your preferred height. A fluffy and comfortable sleeping experience. Uses high-quality low-resilience polyurethane. It gently receives the weight of the head and disperses the pressure concentrated on one point, so it does not impede blood flow and can be expected to relieve stiff shoulders. Moderate resilience maintains an ideal sleeping posture. It is high-density yet breathable, making it less prone to stuffiness and less likely to lose its shape even after long-term use.
